And as a dozen vulnerabilities have been found in the software, one hopes that 400 million people are checking they have updated their copy.

ThreatPost has the details about the vulnerabilities found in builds 7.3.4.311 and earlier of Foxit Reader and Foxit PhantomPDF:

To exploit the vulnerabilities an attacker could use an image file – either a BMP, TIFF, GIF, or JPEG image – to trigger a read memory past the end of an allocated buffer, or object. From there, depending on the vulnerability, an attacker could either leverage the vulnerability as is, or use it in conjunction with other vulnerabilities to “execute code in the context of the current process.”

In other words, an attacker could simply send you a boobytrapped PDF file and if you happened to open it in Foxit’s PDF reader - kaboom!

Alternatively, you could be tricked into visiting a webpage containing a malformed PDF file.

I would understand completely if you have turned your back on Adobe’s PDF reader. The software, and its Adobe Flash Player stablemate, have often been found lacking with exploitable vulnerabilities.

But don’t think that avoiding Adobe Reader means that you somehow have protected yourself from PDF-borne malware. Foxit users would be wise to check that they are running an updated version of the software.

Computer users should update their installations of Adobe Reader and Acrobat as a matter of urgency, after it was discovered that malicious hackers were exploiting a critical zero-day vulnerability in targeted attacks.

The UK branch of the ticketing firm Ticketmaster has warned its online customers that they might have received a series of unauthorised emails after its TicketWeb subsidiary’s mailing list system was compromised.
